Product safety
The table below summarizes the safety instructions that must be observed without fail. A detailed
description can be found in the relevant sections of chapter "General technical information".
Topic Safety information Reference
chapter "General
technical information"
Polarity Make sure that polar capacitors are connected
with the right polarity.

"Basic construction of
aluminum electrolytic
capacitors"
Reverse voltage Voltages polarity classes should be prevented by
connecting a diode.
3.1.6
"Reverse voltage"
Mounting
position of screw-
terminal capacitors
Do not mount the capacitor with the terminals
(safety vent) upside down.
11.1.
"Mounting positions of
capacitors with screw
terminals"
Robustness of
terminals
The following maximum tightening torques must
not be exceeded when connecting screw
terminals:
M5: 2.5 Nm
M6: 4.0 Nm
11.3
"Mounting torques"
Mounting of
single-ended
capacitors
The internal structure of single-ended capacitors
might be damaged if excessive force is applied to
the lead wires.
Avoid any compressive, tensile or flexural stress.
Do not move the capacitor after soldering to PC
board.
Do not pick up the PC board by the soldered
capacitor.
Do not insert the capacitor on the PC board with a
hole space different to the lead space specified.
11.4
"Mounting
considerations for
single-ended capacitors"
Soldering Do not exceed the specified time or temperature
limits during soldering.
11.5
"Soldering"
Soldering,
cleaning agents
Do not allow halogenated hydrocarbons to come
into contact with aluminum electrolytic capacitors.
11.6
"Cleaning agents"
Upper category
temperature
Do not exceed the upper category temperature. 7.2
"Maximum permissible
operating temperature"
Passive
flammability
Avoid external energy, such as fire or electricity. 8.1

chapter "General
technical information"
Active
flammability
Avoid overload of the capacitors. 8.2
"Active flammability"
Maintenance Make periodic inspections of the capacitors.
Before the inspection, make sure that the power
supply is turned off and carefully discharge the
electricity of the capacitors.
Do not apply any mechanical stress to the
capacitor terminals.

"Maintenance"
Storage Do not store capacitors at high temperatures or
high humidity. Capacitors should be stored at
+5 to +35 °C and a relative humidity of 75%.

Breakdown strength
of insulating
sleeves
Do not damage the insulating sleeve, especially
when ring clips are used for mounting.
